Adult male and looks a good match for my Panama ... definitely western ... I would say proximus orarious too. Probably from a Fauna import and advertised as sauritus in the shops most likely.
Could you get me a clearer shot mid-body? As close as poss.

P.S. stubby tails shouldn't cause a problem (it can impede males during mating though). It does mean that the previous owners weren't vigilant enough at shedding times.
